PeroNANOFOOD is a research project focused on the development of advanced nanosensor arrays for real-time, non-invasive monitoring of food spoilage, utilizing tin-based halide perovskite nanocrystals. The project aims to establish a new class of intelligent packaging technologies by integrating colorimetric sensors capable of detecting volatile organic compounds (VOCs) associated with microbial degradation in meat products.

The approach involves the synthesis of non-toxic perovskite nanocrystals with tailored surface chemistry to enable selective interaction with spoilage-related VOCs. These nanocrystals are embedded in polymeric matrices or incorporated into nanoLED configurations, allowing for direct optical readout through visible color change or photoluminescence modulation. Sensor responses are correlated with metagenomic analyses to identify the microbial communities responsible for degradation. By combining nanomaterials engineering, optoelectronic device fabrication, and bioanalytical characterization, PeroNANOFOOD contributes to the advancement of smart packaging solutions that support dynamic shelf-life assessment and microbial traceability. The project addresses key challenges in food safety and waste reduction, aligning with EU priorities on sustainability and circular economy. It is implemented through a collaboration between the National Centre for Scientific Research “Demokritos” (NCSR D) and the Agricultural University of Athens (Team of Prof. P. Skandamis), integrating expertise across materials, sensor technology, and food science.
